Safe Range
Setting up the ASV ventilator is both easy and safe thanks to the Safe Range
Once the animal's body weight has been entered the software computes the median
settings for tidal volume and respiratory rate.These same equations are used to cal-
culate a Safe Range

ume (in liters) is determined by the equation 0.0062 x M b

or equal to ±10% of the calculated tidal volume and respiratory rate. All the default
parameter settings can be overridden. If you enter a setting outside of the Safe Range
for the body mass of the animal to be ventilated you are warned that the value is out-
side the Safe Range™ and asked to confirm the setting.
